Logan, like Clausing, it to be commended for continuing to offer some hardware support for their old machines. The reason that I put the file in DOWNLOADS is the same reason that we encourage members to put photos into an album in PHOTOS first and then link to them in a post. If someone later discovers a need for a parts list, unless they remember enough about the tread where they saw it to search for the thread, there is about zero chance that they will find it again. Embedded files in posts or threads are not searchable for.
By the same token, linking to files or photos from a thread is undesirable. Availability is subject to being lost because the originator lost interest and closed their account, or because the storage site went belly up, or many other reasons..
